Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and more specifically, to a massage chair frame and a massage chair. Background Technology

[0002] With rapid socio-economic development and an increasingly fast pace of life, people enjoy a higher standard of living while also facing mounting work pressure and life burdens. Prolonged desk work and a lack of effective exercise have become common among modern urban dwellers, leading to increasingly prominent sub-health issues such as cervical spondylosis, lumbar strain, muscle stiffness, and poor blood circulation. Against this backdrop, massage chairs with relaxation, soothing, and therapeutic functions are gradually becoming important equipment for home health care, widely used in homes, offices, and wellness facilities.

[0003] The core function of a massage chair relies on the movement of its internal frame mechanism, especially the coordinated tilting, sliding, or zero-gravity posture adjustment of the backrest and seat. Currently, most mainstream massage chairs on the market use multi-link mechanisms or guide rail slider structures to achieve frame movement. However, existing linkage mechanisms have numerous parts, complex assembly, and a disorganized structure; moreover, during frame movement, the user's center of gravity often shifts significantly, causing discomfort during the massage. Utility Model Content

[0004] The purpose of this application is to provide a massage chair frame and a massage chair, which can simplify the structure of the frame and improve the user experience while keeping the center of gravity of the frame unchanged.

[0005] The embodiments of this application are implemented as follows: In a first aspect of this application, a massage chair frame is provided, including a base and a frame disposed on the base. Arc-shaped tubes are respectively disposed on opposite sides of the frame, and guide components are respectively disposed on opposite sides of the base corresponding to the arc-shaped tubes. The guide components include multiple pulleys, which are alternately disposed on both sides of the arc-shaped tubes at intervals, forming a slide between the multiple pulleys. When the frame is driven to rotate, the arc-shaped tubes move within the slide.

[0006] In one possible implementation, the center of the pulley on the outer side of the arc-shaped tube is located on a first circle with radius R1, and the center of the pulley on the inner side of the arc-shaped tube is located on a second circle with radius R1. The first and second circles are concentric, and an arc-shaped groove is formed on the outer circumference of the pulley, with a radius of R. 滑 The radius of the arc-shaped tube is R. 管 The radius of the circle containing the arc-shaped tube is R3, where R1 - R3 = R3 - R2 = R 滑 +R 管 .

[0007] As one possible implementation method, R 滑 =R 管 .

[0008] As one possible implementation, the guide assembly includes three pulleys: one is disposed on the second circle and is the first pulley; the other two are disposed on the first circle and are located on both sides of the first pulley.

[0009] In one possible implementation, the base includes a support member and a connecting plate disposed on the support member. Guide components are disposed on opposite sides of the connecting plate. A driving member is also disposed on the connecting plate. The driving end of the driving member is connected to the frame to drive the frame to move.

[0010] As one possible implementation, the drive element is positioned between two guide components.

[0011] As one possible implementation, ear plates are also provided on the connecting plate and the frame respectively. The driving component is connected to the connecting plate through the ear plates to be rotatably connected to the connecting plate. The driving end of the driving component is connected to the frame through the ear plates to be rotatably connected to the frame.

[0012] As one possible implementation, the guide assembly also includes a mounting plate disposed opposite to the pulley, with both ends of the pulley connected to the mounting plate respectively.

[0013] As one possible implementation, the frame includes a backrest and a seat, the backrest and the seat are connected by a connecting rod, and a reinforcing rod is also provided between the backrest and the seat.

[0014] A second aspect of this application provides a massage chair, including the massage chair frame described above, and a flexible covering disposed on the massage chair frame.

[0015] The beneficial effects of the embodiments of this application include: The massage chair frame provided in this application includes a base and a frame body mounted on the base. Arc-shaped tubes are respectively arranged on opposite sides of the frame body, and guide components are respectively arranged on opposite sides of the base corresponding to the arc-shaped tubes. Each guide component includes multiple pulleys, which are alternately arranged on both sides of the arc-shaped tubes, forming a slide rail. When the frame body is driven to rotate, the arc-shaped tubes move within the slide rails. Through the multi-point envelopment constraint of the arc-shaped tubes by the pulleys, the rotational motion of the frame body is guided into precise movement along a preset arc-shaped trajectory, achieving coordinated tilting or zero-gravity posture adjustment of the chair back and seat cushion. Compared to the complex linkage or linear guide rail mechanisms of existing technologies, this method has advantages such as fewer parts, simpler assembly, smoother operation, and lower friction noise. Simultaneously, the arc-shaped trajectory can match the natural changes in the human body's center of gravity, effectively reducing forward slippage or imbalance during massage, significantly improving comfort, reliability, and user experience. Therefore, this massage chair frame simplifies the structure of the chair frame and improves the user experience while maintaining the center of gravity position of the frame.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Please refer to the reference. Figure 1 and Figure 2 This application provides a massage chair frame 100, including a base 110 and a frame 120 disposed on the base 110. Arc-shaped tubes 131 are respectively disposed on opposite sides of the frame 120. Guide components 140 are respectively disposed on opposite sides of the base 110 corresponding to the arc-shaped tubes 131. The guide components 140 include multiple pulleys 142, which are alternately disposed on both sides of the arc-shaped tubes 131, forming a slide between the multiple pulleys 142. When the frame 120 is driven to rotate, the arc-shaped tubes 131 move within the slide.

[0023] The massage chair frame 100 provided in this embodiment serves as a support structure for the massage chair. Specifically, the massage chair frame 100 includes a base 110 and a frame 120 mounted on the base 110. The base 110 serves as the fixed base of the entire massage chair, and the frame 120, mounted on the base 110, supports the massage components and seat cushion, and rotates relative to the base 110 when driven. Specifically, arc-shaped tubes 131 are respectively provided on opposite sides of the frame 120, and guide components 140 are respectively provided on opposite sides of the base 110. The arc-shaped tubes 131 extend into the guide components 140 and rotate under the guidance of the guide components 140. More specifically, the guide components 140 include multiple pulleys 142, which are alternately arranged on both sides of the arc-shaped tubes 131, mostly placed in slide tracks, and rotate within the slide tracks, thereby realizing the rotation of the frame 120 relative to the base 110.

[0024] During massage in this embodiment of the massage chair, the drive unit 151 drives the frame 120 to rotate. When the frame 120 rotates, the arc-shaped tubes 131 on both sides of the frame 120 move accordingly. Their outer surfaces contact the slide rails on the base 110, which are composed of multiple pulleys 142. Since the pulleys 142 are alternately arranged on both sides of the arc-shaped tubes 131, they can limit and support the arc-shaped tubes 131 from multiple directions, preventing them from falling out or shaking. When the arc-shaped tubes 131 rotate in the slide rails, the center of gravity of the massage chair frame 100 is kept in a certain position, thereby improving the user experience.

[0025] The massage chair frame 100 of this embodiment uses multiple pulleys 142 alternately arranged on both sides of the arc-shaped tube 131 to form a slide rail for the arc-shaped tube 131, enabling the frame 120 to rotate relative to the base 110. The structure is simple. In summary, the massage chair frame 100 of this embodiment simplifies the structure of the chair frame and improves the user experience while maintaining the center of gravity of the frame.

[0026] The massage chair frame 100 includes a base 110 and a frame 120 mounted thereon. The frame 120 has arc-shaped tubes 131 on opposite sides. Guide components 140 are positioned correspondingly on the base 110. Each guide component 140 includes multiple pulleys 142, which are alternately arranged on the inner and outer sides of the arc-shaped tubes 131, forming a slide that conforms to the contour of the arc-shaped tubes 131. When the frame 120 rotates under the action of the drive component 151, the arc-shaped tubes 131 on both sides slide smoothly along the slide. Its working principle is as follows: by using the pulleys 142 to constrain the arc-shaped tubes 131 at multiple points, the rotational motion of the frame 120 is guided into precise movement along a preset arc-shaped trajectory, achieving coordinated tilting or zero-gravity posture adjustment of the chair back and seat cushion. This structure abandons the traditional complex linkage or linear guide mechanism, and has the advantages of fewer parts, simple assembly, smooth operation and low friction noise. At the same time, the arc trajectory can match the natural changes in the human body's center of gravity, effectively reducing the feeling of the body sliding forward or losing balance during the massage, and significantly improving comfort, reliability and user experience.

[0027] Optional, such as Figure 2 and Figure 5 As shown, the center of the pulley 142 on the outer side of the arc-shaped tube 131 is located on the first circle O1 with a radius of R1, and the center of the pulley 142 on the inner side of the arc-shaped tube 131 is located on the second circle O2 with a radius of R1. The first circle O1 and the second circle O2 are concentric. An arc-shaped groove 143 is formed on the outer periphery of the pulley 142, and the radius of the arc-shaped groove 143 is R. 滑 The radius of the arc-shaped tube 131 is R. 管 The radius of the circle containing the arc-shaped tube 131 is R3, where R1 - R3 = R3 - R2 = R 滑 + R 管 .

[0028] In this context, the inner side of the arc-shaped tube 131 refers to the side of the arc-shaped tube 131 closest to the center of the circle containing the arc-shaped tube 131, i.e., the area enclosed by the arc-shaped tube 131; conversely, the outer side of the arc-shaped tube 131 refers to the side of the arc-shaped tube 131 furthest from the center of the circle containing the arc-shaped tube 131, i.e., outside the area enclosed by the arc-shaped tube 131. The center of the pulley 142 on the outer side of the arc-shaped tube 131 is located on the first circle O1 with radius R1, meaning that the line connecting the center points of the pulleys 142 on the outer side of the arc-shaped tube 131 lies on a certain arc, and the radius of the circle containing this arc is R2. The radius of the arc-shaped tube 131 is R. 管 This refers to the radius R of the circle containing the centerline of the arc-shaped tube 131. 管 .

[0029] From R1-R3=R3-R2=R 滑 +R 管 We can obtain that R1 = R3 + (R 滑 +R 管 ) and R2=R3-(R 滑 +R 管 The first circle O1 and the second circle O2 are arranged symmetrically about the center line of the arc-shaped tube 131. Furthermore, the radius difference between the first circle O1 and the second circle O2 is R. 滑 +R 管 This arrangement ensures that both sides of the arc-shaped tube 131 abut against the inner walls of the pulleys 142, resulting in a tight fit between the arc-shaped tube 131 and the pulleys 142 on both sides, without gaps or interference. The outer pulley 142 encloses the arc-shaped tube 131 from the outside, while the inner pulley 142 abuts against it from the inside. Multiple pulleys 142 are arranged alternately along the arc length, forming a multi-point enveloping constraint, effectively preventing the arc-shaped tube 131 from derailing, wobbling, or twisting during movement. Precise guidance is achieved between the pulleys 142 and the arc-shaped tube 131 through the conformal contact between the arc-shaped groove 143 and the tube wall, resulting in high guidance accuracy and smooth operation. Furthermore, the symmetrical support of the inner and outer pulleys 142 ensures balanced load distribution, preventing unilateral wear and extending the service life of the massage chair frame 100.

[0030] In addition, it is understandable that the circle containing the arc-shaped tube 131 is concentric with the first circle O1 and the second circle O2.

[0031] As an feasible approach, such as Figure 3 As shown, R 滑 =R 管 .

[0032] When the arc-shaped tube 131 is located in the slide, it abuts against the side wall of the arc-shaped groove 143, reducing the radius R of the arc-shaped groove 143. 滑 The radius R of the arc-shaped tube 131 管 With the same configuration, the groove of the pulley 142 and the outer surface of the arc-shaped tube 131 form a completely conformal cylindrical surface contact.

[0033] During movement, the outer wall of the arc-shaped tube 131 fits precisely against the inner contour of the groove in the pulley 142, with both having the same curvature. This results in continuous and stable surface or near-surface contact in the contact area, effectively distributing the load and reducing local pressure. This significantly improves the operational stability and wear resistance of the guiding system, while greatly reducing frictional resistance and operating noise. Furthermore, because the fit clearance is controllable and wobble-free, the frame 120 maintains a precise and vibration-free trajectory during tilting and rotation, further enhancing the comfort and reliability of the massage chair's posture adjustment.

[0034] Optional, such as Figure 2 and Figure 5 As shown, the guide assembly 140 includes three pulleys 142, one of which is set on the second circle O2 and is the first pulley 142, and the other two are set on the first circle O1 and are located on both sides of the first pulley 142 respectively.

[0035] The guide assembly 140 includes three pulleys 142. A first pulley 142 is positioned on a second circle O2 with radius R2, located inside the arc-shaped tube 131. The other two pulleys 142 are symmetrically positioned on a first circle O1 with radius R1, also inside the arc-shaped tube 131, and are respectively arranged on both sides of the first pulley 142 along the arc-shaped trajectory, forming an inner and outer triangular clamping layout. During operation, the arc-shaped tube 131 is constrained by these three pulleys 142 from both the inner and outer sides. Specifically, the inner first pulley 142 provides centripetal support to prevent the arc-shaped tube 131 from slipping outwards; the two outer pulleys 142 clamp and guide its movement trajectory from the outside. Together, they form a stable three-point contact envelope structure, ensuring that the arc-shaped tube 131 slides smoothly along a path with a preset curvature radius R3 during the rotation of the frame 120. This simplifies the structure by using only three pulleys 142 while maintaining high guiding accuracy.

[0036] As an feasible approach, such as Figures 1 to 6 As shown, the base 110 includes a support member 111 and a connecting plate 112 disposed on the support member 111. The guide assembly 140 is disposed on opposite sides of the connecting plate 112. The connecting plate 112 is also provided with a driving member 151. The driving end of the driving member 151 is connected to the frame 120 to drive the frame 120 to move.

[0037] The base 110 of this application includes a support member 111 and a connecting plate 112 fixed thereon. Guide components 140 are respectively disposed on opposite sides of the connecting plate 112 to guide the movement trajectory of the arc-shaped tubes 131 on both sides of the frame 120. Simultaneously, a drive component 151 is integrated on the connecting plate 112, with its drive end directly connected to the frame 120. During operation, the drive component 151 generates thrust or pull, driving the frame 120 to move, while the arc-shaped tubes 131 on both sides of the frame 120 slide synchronously within the slide rails of the guide component 140, achieving smooth tilting or attitude adjustment. Sharing the same connecting plate 112 mounting platform for the guide component 140 and the drive component 151 simplifies the overall structural layout, improves assembly accuracy and rigidity, and effectively ensures the consistency between the drive action line and the guide trajectory, avoiding jamming or wear caused by force eccentricity.

[0038] Specifically, the specific structure of the drive component 151 is not limited in this application embodiment. For example, it can be an electric actuator or a motor.

[0039] Optional, such as Figure 2 and Figure 4 As shown, the drive element 151 is disposed between the two guide components 140.

[0040] The driving component 151 is positioned between the two guide components 140, specifically at the midpoint of the two sets of pulleys 142 guiding structures corresponding to the arc-shaped tubes 131 on both sides of the frame 120 on the connecting plate 112. Its driving end is directly connected to the frame 120. This arrangement ensures that the line of action of the output force of the driving component 151 roughly passes through the center of motion symmetry of the frame 120, achieving a high degree of spatial coordination with the guiding trajectory of the arc-shaped tubes 131. During operation, the driving force generated by the extension, contraction, or rotation of the driving component 151 is evenly transmitted to the frame 120, propelling it to rotate smoothly along the arc-shaped path defined by the guide components 140. Meanwhile, the guide components 140 on both sides simultaneously constrain the motion posture of the arc-shaped tubes 131, preventing swaying or twisting. This centrally driven, two-sided guided structural design effectively avoids problems such as excessive force on one side, uneven wear of pulley 142, or movement stagnation caused by eccentric driving force, significantly improving the stability, synchronization, and durability of the system operation; at the same time, the overall layout is compact and the force is reasonable, which is conducive to optimizing the internal space of the massage chair and improving the overall reliability of the machine.

[0041] As an feasible approach, such as Figure 2 , Figure 4 and Figure 6 As shown, the connecting plate 112 and the frame 120 are respectively provided with ear plates 161. The driving component 151 is connected to the connecting plate 112 through the ear plate 161 so as to be rotatably connected to the connecting plate 112. The driving end of the driving component 151 is connected to the frame 120 through the ear plate 161 so as to be rotatably connected to the frame 120.

[0042] Both the connecting plate 112 and the frame 120 are provided with ear plates 161. The driving component 151 is rotatably connected to the connecting plate 112 via the ear plates 161, and its driving end is also rotatably connected to the frame 120 via the ear plates 161, thus forming a linkage-type driving structure with hinged ends. During operation, the driving component 151 can freely rotate around the pins of its respective ear plates 161 during extension and retraction, adapting to the continuous angle changes of the frame 120 in its arc-shaped trajectory movement, avoiding interference or additional bending moments caused by rigid connections. This not only ensures efficient and smooth transmission of driving force but also significantly improves the movement flexibility and reliability of the mechanism. At the same time, the hinged connection effectively absorbs assembly errors and minor deformations during operation, reducing wear and noise and extending service life.

[0043] Optional, such as Figure 1 , Figure 4 and Figure 6 As shown, the guide assembly 140 also includes a mounting plate 144 disposed opposite to it, and the two ends of the pulley 142 are respectively connected to the mounting plate 144.

[0044] The guide assembly 140 also includes mounting plates 144 disposed on both sides thereof. The two ends of each pulley 142 are fixedly connected between the two mounting plates 144 via shafts or bearings, forming a stable frame mounting structure. During operation, the arc-shaped tube 131 moves within the arc-shaped groove 143 on the outer periphery of the pulley 142, while the pulley 142 itself is firmly clamped between the two mounting plates 144, ensuring precise positioning, flexible rotation, and preventing skewing or detachment. This improves the overall rigidity and assembly accuracy of the pulley 142 assembly, effectively bearing the radial and lateral loads generated during the movement of the frame 120; simultaneously, the modular mounting plate 144 structure facilitates the pre-assembly, debugging, and subsequent maintenance of the pulley 142.

[0045] As an feasible approach, such as Figure 1 and Figure 2 As shown, the frame 120 includes a backrest and a seat, which are connected by a connecting rod 145, and a reinforcing rod 146 is also provided between the backrest and the seat.

[0046] The frame 120 includes a backrest and a seat, which are fixedly connected by a connecting rod 145 to form a coordinated overall support structure. A reinforcing rod 146 is added between the backrest and the seat to form a triangular reinforced frame. During operation, when the drive component 151 drives the frame 120 to tilt or slide, the drive component 151 connects with the connecting rod 145, allowing the connecting rod 145 to transmit the motion relationship to achieve backrest and seat linkage. The reinforcing rod 146 effectively suppresses relative deformation or swaying between the backrest and the seat through tension and compression, significantly improving overall rigidity. This ensures the stability and consistency of the user's body support during massage, avoiding a feeling of collapse or abnormal noise caused by excessive flexibility of the frame 120. It also enhances the load-bearing capacity and fatigue life of the mechanism, while helping to accurately transmit drive movements, making posture adjustment smoother and more reliable.

[0047] In a second aspect, this application also provides a massage chair, including the massage chair frame 100 described above, and a flexible covering disposed on the massage chair frame 100. This massage chair has the same structure and beneficial effects as the massage chair frame 100 in the foregoing embodiments. The structure and beneficial effects of the massage chair frame 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0048] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0049] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
